I have Focal 165K Component set but I have lost the crossover- is there a crossover built into the base system already ( I do not have the bose)

Any solutions? I do not intend to use an amp- just the focal components attached to the stock radio.

Thanks for the help.

 

There is no crossover included in the base system. Sorry but I can't help with finding a crossover - perhaps others will be able to suggest something.
